Pipe wall thinning in the secondary piping system of a nuclear power plant is currently a major problem that typically affects the safety and reliability of the nuclear power plant directly.Regular in-service Osram QTi Dimmable Ballasts inspections are carried out to manage the piping system only during the overhaul.Online thickness monitoring is necessary to avoid abrupt breakage due to wall thinning.To this end, a transducer that can withstand a high-temperature environment and should be installed under the insulation layer.We propose a thin plate type Toys of embedded ultrasonic transducer based on magnetostriction.
The transducer was designed and fabricated to measure the thickness of a pipe under a high-temperature condition.A number of experimental results confirmed the validity of the present transducer.
